Active phosphate flotsam : Tetramethylphosphonium cations can be prepared in the cages of HSAPO‐34 catalysts from PH 3 and methanol by using a ship‐in‐a‐bottle approach (see picture). Calcination of this material leaves phosphate debris in some of the cages, which produces an active methanol‐to‐olefin catalyst with improved ethylene selectivity.
